INVISIBLE OPTION!

You see, sometimes I get online, and I just want to be left alone (aka if I need to play ONE more game in my series, but 10 of my other friends are online). It's a pretty common thing in games to have an "Invisible" option for a player, just so they can continue to play the game, but in incognito mode. I'd love it if League could have this option, because sometimes, I just want to game alone. JA' FEEL?!
